Types and Parts of Plants
What types of plants have we investigated this unit?
Grass, flowers, bushes, trees
Why do plants complete the process of photosynthesis?
To make their food.
Give an example of a flowering plant and a non-flowering plant.
Flowering: Sunflower, tomato plant, apple tree
Non-flowering: Pine tree, moss, fern
What are the six human influences on nature that we investigated?
Pollution, agriculture, construction, tourism, deforestation, and transportation.
What three conjunctions have we practiced this unit?
and, but, or
What are the three main parts that all plants have?
Roots, trunk/stem, leaves.
What parts of a plant are used for photosynthesis.
Roots, stem/trunk, and leaves.
What are some examples of plants that reproduce sexually or asexually?
Sexual: Pear tree, daisies, pine tree, sunflower, etc.
Asexual: potatoes, garlic, onion, tulips, spider plant, etc.
What different types of pollution are there?
Air, water, and land
Invent a sentence using one of the conjunctions we studied.
For example: Non-flowering plants can have seeds or spores.
Explain the difference between the types of plants we studied.
Tree: Are tall with a rigid trunk. Lots of branches and leaves or needles.
Bush: Shorter with lots of branches and leaves.
Grass: Short, flexible stem and leaves.
Flower: Part of other plants. Have petals and pollen. A flexible stem and some leaves.
What ingredients do plants need to complete photosynthesis?
Water, vitamins and minerals, sunlight, and carbon dioxide.
Explain the difference between flowering and non-flowering plants.
Flowering plants: They have flowers that grow into fruits. In the flowers or fruits there are seeds. The seeds spread by wind or animals.
Non-flowering plants: They don't have flowers. They have seeds in cones or spores. They spread by the wind.
Thing of this scenario: A farmer grows food for the city, but uses a lot of chemicals on the crops. Now name one positive effect and one negative effect.
Positive: People have food. The farm has a job.
Negative: Chemicals can pollute water or hurt animals.
What are conjunctions?
Words we use to connect ideas in a sentence.
What's the difference between a trunk and a stem.
A trunk is bigger and more rigid. A stem in smaller and more flexible. Trees have trunks.
Can most plants complete photosynthesis at night? Why or why not?
No, most cannot because they need sunlight.
Explain the difference between sexual plant reproduction and asexual plant reproduction.
Sexual plant reproduction: Plants reproduce with the help of another plant (pollination)
Asexual plant reproduction: Plants reproduce by themselves.
What are some things that we can do better, at school or in our houses, to improve our influence in nature?
For example: we can recycle, we can use both sides of our notebook pages, we can throw our trash in the bin, we can bring a reusable tupperware container, etc.
Explain when we use the conjunction "and".
We use "and" when we connect ideas that are the same or similar.
Thinking about patterns we investigated, explain what the 3 main parts of a plant do?
Roots: Holds the plant in the ground, absorbs water and nutrients from the soil.
Trunk/stem: Supports the plant, transports the water and nutrients to the rest of the plant.
Leaves: Absorbs sunlight and carbon dioxide, where the plant makes its food.
Explain all the steps of photosynthesis.
1. The roots absorb water, vitamins, and minerals from the soil.
2. The stem/trunk transports the water and nutrients to the rest of the plant.
3. The leaves absorb sunlight and carbon dioxide. The "ingredients" mix.
4. The plant makes its own food and produces oxygen
Explain the process of pollination.
1. Pollinators (insects, small animals, etc.) go to a flower.
2. The pollen sticks to their bodies.
3. They bring this pollen to another flower.
4. They leave this pollen in a new flower.
5. This helps create new seeds.
6. A new plant grows.
Explain one type of human influence in nature. What is it? How is it positive or negative?
Construction: It is when people build new buildings or roads. It helps create towns where people can live and new jobs. It can also destroy habitats and pollute the air, water, and land.
Explain when we use the conjunction "but".
We use "but" to connect two ideas that are contrasting, or different.
