The reactants are water, carbon dioxide, and energy from the sun. The products are glucose and oxygen.
The colorful parts of the flower that attract pollinators
What are petals?
A plant's response to harsh winter conditions
What is dormancy?
What are the three main categories into which all plants can be divided?
Nonvascular, seedless vascular, and seed plants
A green pigment in plants that is used to convert the sun's energy into food for the plant
What is chlorophyll?
What happens during transpiration?
Water evaporates directly from a plant's leaves.
The male reproductive structure of the flower that contains pollen
What is the stamen?
A plant's response to gravity
What is gravitropism?
What is the difference between gymnosperms and angiosperms?
Gymnosperms produce naked seeds in cones while angiosperms produce flowers with seeds that become enclosed in fruit.
Vascular tissue the carries food
What is phloem?
What happens during pollination?
Pollen is transferred from the male structure of one flower to the female structure of a different flower.
The female reproductive structure of the flower that receives pollen
What is the pistil or stigma (part of the pistil)?
A plant's response to light
What is phototropism?
What is the difference between monocots and dicots?
Monocots have one cotyledon or seed leaf while dicots have two cotyledons or seed leaves.
Vascular tissue that carries water
What is xylem?
What happens during fertilization in seedbearing plants?
The part of the flower in which the seeds are formed and which turns into a fruit
What is the ovary?
A plant's response to touch
What is thigmotropism?
What is the difference between annuals and perennials?
Openings in the underside of a leaf that allow water and gases to enter or exit the leaf
What are stomata?
An embryo begins to push out of the seed and grow into a plant.
The three parts of a seed
What are the seed coat, embryo, and cotyledon
A plant's response to the changes in the length of night and day
What is photoperiodism?
How are nonvascular plants different from vascular plants? Give two examples.
Nonvascular plants do not have true roots, stems, and leaves while vascular plants do. Nonvascular plants cannot grow tall while vascular plants can.
