What is food?
a growth response of an organism toward or away from a stimulus
What is tropism?
True or false?
In asexual reproduction of plants, a new plant grows from a part of the parent plant and it's genetic material is a combination from both parents.
What is false?
process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and glucose (sugar)
What is photosynthesis?
Process that releases energy by breaking down glucose into a usable energy (ATP)
What is cellular respiration?
the products of photosynthesis
What are glucose and oxygen?
True or false?

Which comes first, pollination or fertilization?
What is pollination?
vascular tissue that carries water upward from the roots to every part of a plant
What is xylem?
the alternation between the haploid gametophyte and the diploid sporophyte in a plant's life cycle
What is alternation of generations?
the organelle where photosynthesis takes place that contains chlorophyll
What are chloroplasts?
______________ are a plant hormone that can make a plant grow faster and larger
What are gibberellins?
Name something that gymnosperms and angiosperms have in common.
They both produce seeds and reproduce sexually.
The vascular tissue through which food moves in some plants
What is phloem?
A plant that produces seeds that are exposed rather than seeds enclosed in flowers or fruits
What are gymnosperms?
the products of cellular respiration?
What are carbon dioxide, water, and ATP?

What is a poinsetta?
Name the 3 main parts of a seed.
What are embryo, protective covering, and food supply?
a plant's response to the number of hours of darkness in its environment
What is photoperiodism?
