ROOTS, STEMS, AND LEAVES Plants have structures that serve different purposes for keeping the plant alive and healthy. Let’s start from the bottom up, with the ROOTS: The roots of a plant have three jobs to do: • to anchor the plant firmly into the soil, • to store food, and most importantly, • to absorb water and nutrients from soil. Plants have two different root systems. A taproot system consists of one main large root that grows directly down into the soil. A fibrous root system consists of many roots that grow underground in many directions. Taproot Fibrous Roots Next, the STEM: The stem also has several jobs. It helps the plant reach up tall which enable the plant to take in more sunlight. The stem also carries food, water, and nutrients all throughout the plant. All parts of a plant need food, water, and nutrients. These essential necessities get to all parts of the plant through the tissues in the plant, called the xylem and phloem. © Copyright NewPath Learning. All Rights Reserved.

Vascular plants have special tubes that carry food, water, and nutrients throughout a plant. The xylem is the tube that carries water and nutrients from the roots to leaves. The phloem carries sugar away from leaves to the rest of the plant. Now to the LEAVES: Most of a plant’s food is made in its leaves. Leaves of a plant are made of plant organs and tissues. The top layer of leaf, which protects the leaf, is called its epidermis. Leaves have tiny openings underneath them called the stomata which let air and water in and out of the leaf. Lesson Checkpoint: What three jobs do roots do for the plant? How do plants reproduce? Flowering plants reproduce using seeds. A flowering plant uses several parts in the reproduction process. The stamen is the male part of the flower. Pollen forms on top of each stamen. The pistil is the female part of flower. A flower may have more than one pistil or stamen. Pollen is the plant substance that needs to be transferred from one flower’s stamen to the pistil of another flower in order for plant reproduction to occur. Pollination is the movement of pollen from one flower to another. Flowers pass along their hereditary information in seeds. The seeds thus contain all the information for reproducing the flower, stem, leaves, and roots of a plant © Copyright NewPath Learning. All Rights Reserved.

A seed is made up of three parts: a seed coat, embryo (which is a new plant ready to grow), and endosperm. Spores, asexual reproduction (reproduction involving only one parent), budding, and runners are all ways some plants reproduce without seeds. Lesson Checkpoint: What is pollination? Plants make their food through the process of photosynthesis Plant makes sugar for food through the process of photosynthesis. All cells need energy to function and live; through the process of photosynthesis sugar gets sent to all the cells in the plant. Sugar is used for energy and for forming cellulose – a chemical that makes up plant cell walls. The more sunlight the plant absorbs, the more sugar the plants make. Photosynthesis occurs in the chloroplast of a plant cell, where the plant absorbs sunlight. Plants use carbon dioxide they take in from the air around them, water they get from the soil through their roots, and energy from the sun to produce sugar and oxygen. Plants release the oxygen, which they don’t need, into the air for us aerobic organisms, who need oxygen to survive.

5.1. Plants
Plants are living things that need water, air, nutrients and sunlight to grow. There are two main kinds of plants - plants with flowers and plants without flowers. Plants with flowers include fruit trees and any plant with flowers. Plants without flowers include pine trees, mosses and ferns.
5.2. Main Parts of Plants
A plant has many important parts, such as roots, stem, leaves and flowers. Each part of the plant has different functions that make it possible for the plant to live.
5.3. Roots
Roots help support the plant by anchoring it into the ground. Roots have tiny hairs that absorb nutrients from the soil, which a plant needs to grow. These root hairs also take in water from the soil, which a plant needs to live and grow.
5.4. Stem
A plant's stem is used to support the plant. The stem allows the plant's leaves to reach above the soil so that they may take in the sunshine. A plant's stem carries the water and nutrients that are taken in by the plant's roots to the rest of the plant.
5.5. Leaves
Leaves are the parts of a plant where the plant's own food is made. They use sunlight, air, water and nutrients from the soil to make their own food through a process called photosynthesis.
5.6. Flowers
The main job of the flower of a plant is to make seeds. New plants grow from these seeds. Some plants form fruit to help protect their seeds.

5.8. What a plant needs to grow...
Plants need many essential things in order to grow, such as water, air, nutrients, sunlight, and warm temperature. Plants need their space too!
5.9. Germination
Germination is the process by which the plant embryo inside a seed grows and a seedling grows above the soil. A seedling is a young plant that is in its early stages of growth.
5.10. Plants have different life cycles...
Living things have different life cycles. A life cycle is the way a living thing grows and changes. A flowering plant's life cycle describes the steps a plant takes to grow and become an adult plant.
5.11. Bean Plant Life Cycle
A bean plant's life cycle includes four stages: 1. Seed - contains the embryo, which will develop into the plant; 2. Sprouting seed - germinates or grows root and stem; 3. Seedling- its first leaves make food 4. Mature plant- can make seeds that will begin the life cycle again!

5.13. Animals
There are many different kinds of animals. Animals are grouped into two kinds - animals with backbones and animals without backbones.
5.14. Animals with backbones
Animals with backbones include mammals, birds, fish, amphibians and reptiles.
5.15. Animals without backbones
Most kinds of animals do not have backbones. Animals without backbones include insects, worms, crabs, spiders and many others.
5.16. Animal Growth & Reproduction
Animals produce offspring in a variety of ways. For example, many animals have live births. The offspring develop inside the female parent which then gives birth to the live young. Other organisms, like chickens and frogs, lay eggs instead of having live births. Animal life cycles vary in how long they take.
5.17. Frog Life Cycle
Like all amphibians, frogs spend their lives near water because they must return to water to lay their eggs. The four stages of a frog's life cycle include: 1. Frog eggs are laid in water. 2. Tadpoles hatch from the eggs. They breathe with gills and swim using a tail. 3. The froglet still has part of its tail and starts to breathe using its lungs. 4. By the time a froglet becomes an adult, its tail is reabsorbed.

5.19. Butterfly Life Cycle
Butterflies and moths go through complete metamorphosis and undergo four stages of development: egg, larva (caterpillar), pupa (Chrysalis), and adult.

5.21. Dragonfly Life Cycle
Most insects go through complete metamorphosis, but some, such as dragonflies, go through incomplete metamorphosis. This life cycle includes three stages of development: egg, nymph, and adult.

5.23. Inheritance of Traits
Have you ever wondered why offspring , the young of a plant or animal, often look like their parents? This is due to the inheritance of traits, which means that parents pass on their traits to their offspring. Animals inherit traits such as the shape and color of their body parts. Plants inherit traits such as leaf shape and flower color.
5.24. Animal Variation Due to Inherited Traits
Some offspring may appear different than one or both parents. This is because the offspring receive traits from both parents resulting in a unique combination that is different from either parent. Variations in humans are height and eye color. A child's parents may both have brown eyes, yet the child could have blue eyes.
5.25. Variation Due to Environment
Characteristics of plants and animals can be affected by their surroundings, climate or diet. For example, if you eat too much you will become heavier, and if you eat too little you will become lighter. A plant in the shade of a big tree will grow taller as it tries to reach more sunlight.
5.26. Variation Interactive Matching Activity
5.27. Adaptation
An adaptation is a trait or characteristic that helps a living thing survive in its environment. For example, it takes special adaptations to be able to live in a very cold environment. Polar bears have thick blubber and dense fur to help keep them warm.
