Plants Flashcards
(27 cards)
Abiotic factors
Nonliving part of a biome
Adaptation
A structure or behavior that helps an organism live in its environment
Asexual Reproduction
One parent plant. Plants produced this way are an exact copy of the parent plant
Biome
A part of the world that is categorized by the types of organisms that live there and its climate
Biotic Factors
Living parts of a biome
Cellular Respiration
Process where plants break down sugars to get energy
Chlorophyll
A green substance that absorbs energy from sunlight during photosynthesis
Chloroplasts
Special structures that are unique to plant cells, where the plant’s food-making process takes place
Controlled Variables
Factors or conditions that are kept constant or the same
Dependent Variable
The subject or thing that is being investigated. It is affected by the independent variable
Guard Cells
Control when stomata open and close. Prevents stomata from giving off too much water
Hypothesis
An explanation or idea about something observed that can be tested
Independent Variable
A condition or factor that the investigator can change
Nonvascular plants
Do not have the structures (roots, stems, leaves)
Phloem
Transports food that the plant has made
Photosynthesis
Process that allows plants to make their own food
Pistil
Female part of a flower
Pollen
Produced by the stamen which contains male reproductive cells
Pollination
Occurs when pollen is carried from the stamen to the stigma and seeds form in the ovary
Scientific Method
Investigations by scientists in order to answer questions
Sexual Reproduction
Combines genetic material from male cells and female cells. The offspring have features from both parent plants
Stamen
Male part of a flower
Stomata
Tiny openings in plant leaves that allow the plant to take in carbon dioxide
Thigmotropism
Adaptation that some plants have that allows them to respond to touch
