plant growth response to a stimulus in the environment
What is tropism?
100
the cellular structure that contains the pigment chlorophyll and does photosynthesis
What is a chloroplast?
100
process in which plants make their own food (glucose) by converting light energy, carbon dioxide and water into glucose and oxygen
What is photosynthesis?
100
shed needles through out year, stay green all year and have thick cuticles to protect from freezing and water loss during the dry winter; examples include pines and holly
What is an evergreen tree?
100
process of seeds sprouting
What is germination?
200
plant growth in response to light
What is phototropism?
200
Male and female reproductive structures of flowering plants
What is stamen and pistil?
200
Process in which plants use oxygen to break down glucose to release stored energy for the cell to use
What is cellular respiration?
200
leaves change color in the fall and drop all leaves at the same time to protect from dry winters and conserve energy
What is deciduous tree?
200
Three main parts of a seed
What is seed coat, cotelydon, embryo?
300
plant growth in response to gravity
What is gravitropism or geotropism?
300
Four main parts of a flowering plant
What is roots, stem, leaves, flowers?
300
The process of pollen being transferred from anther to stigma
What is pollination?
300
Plants that flower when nights are long
What is short day plants?
300
seeds develop from this structure and are protected by a fruit formed from this structure
What is ovule... ovary?
400
A plant's shoots grow away from gravity
What is negative gravitropism?
400
This structure contains the ovule with an egg inside
What is the ovary?
400
Process of the sperm from pollen traveling down a pollen tube and fusing with the egg contained in the ovule
What is fertilization?
400
plants that flower when nights are short
What is long day plants
400
Three things seeds need for germination
What is water, warm temps, and air?
500
A plant's shoots grow toward the light from a window
What is positive phototropism?
500
This structure contains the sperm and is found on the anthers of the stamen
What is pollen (pollen grains)?
500
Process of water vapor exiting the leaf through the stomata
What is transpiration?
500
plants that reproduce asexually have one of these structures
What is tubers, runners, and plantlets?
500
A seed that does not germinate because environmental conditions are not right
