Life Cycle of a Plant
100
What are living things made of?
What is cells that are organized into tissues and organs
100
What is photosynthesis?
What is the process of making sugar
100
What is the role of the leaf?
What is to produce food so the plant can survive in its environment
100
What are the four main parts of a flower?
What is sepals, petals, stamens, and pistils
100
Where does a seed get energy to start growing?
What is from food stored inside the seed
200
What are two things that plants need in order to live, grow, and reproduce?
What is sunlight and water
200
Describe the process that occurs during photosynthesis.
What is plants use carbon dioxide that their leaves absorb from the air and water that their roots absorb from the soil. The water and the nutrients travel through tubes in the stem to the leaves. The plants use sunlight energy to change these ingredients into food.
200
What are the two main roles of stems?
What is they carry water, minerals, and food between the roots and the leaves, and they support the plant.
200
What is the main function of the stamen?
What is to make pollen
200
What three conditions are necessary for a seed to grow?
What is water, oxygen, and the right temperature to grow
300
In addition to sunlight and water, plants also need the two following things
What is carbon dioxide from the air and mineral nutrients from the soil
300
What is chlorophyll?
What is the substance in plants that makes them green
300
What are three plant organs?
What is roots, stems, and leaves
300
What guides an animal to a flower?
What is the color of the flowers' petals and the scent of the flower attract and guide the animal to the nectar
300
What might happen if a seed does not get the right conditions for growth to occur?
What is the seed will not germinate
400
How is a giant redwood tree in California like a small dandelion in your backyard?
What is both are living things that are made of many cells, they are multicelled organisms, and they belong to the plant kingdom.
400
What else does chlorophyll do?
What is captures energy from the sunlight so that the plant can change water, carbon dioxide gas, and mineral nutrients from the soil into oxygen, sugar, and other foods.
400
Why are most leaves flat on top?
What is to catch as much sunlight as possible
400
What two things must happen before fertilization takes place?
What is pollen must travel from the stamens to the pistil, and sperm cells must travel to the ovary
400
What happens after a spore germinates?
What is the spore grows into a plant with male and female cells
500
A redwood tree and a dandelion are both plants made of plant cells. How can a redwood tree grow to be so much bigger than a dandelion?
What is it has more cells
500
Where does photosynthesis take place?
What is in the chloroplasts of leaf cells
500
What is the role of the root?
What is they anchor the plant firmly to the ground and some store food
500
Why do animals play an important role in plant reproduction?
What is animals carry pollen from the stamen to the pistil, where fertilization takes place
500
Describe the stages in the life cycle of a tomato.
What is First, the tomato seed germinates, with the seeds absorbing water and the seed coat splitting open. Then, the plant uses the food inside the seed to grow, and the roots grow both down into the soil and up to the light. Next, leaves begin to make food for the plant, and the stem and leaves begin to grow. Then, the plant grows into an adult plant and flowers begin to grow. Next, the flower makes egg cells and pollen, pollination occurs, and the fertilized eggs develop into seeds. Finally, the fruit forms around the seeds, the fruit and seeds separate from the plant and the seeds germinate, beginning the cycle again.
