Nutrition In Plants Flashcards
(16 cards)
What is the primary function of nutrients in plants?
To enable life processes and build body structures
Nutrients are essential for the growth and development of plants.
What is autotrophic nutrition?
Nutrition in organisms that produce their own food
Autotrophs, such as plants, use sunlight or chemicals to synthesize organic compounds.
What are heterotrophic organisms?
Organisms that obtain nutrients by consuming other organisms
Heterotrophs include animals that eat plants or other animals.
What is the role of chlorophyll in plants?
To absorb light energy for photosynthesis
Chlorophyll is found in the chloroplasts of plant cells.
Fill in the blank: The outer layer of plant cells is called the _______.
cell membrane
What is the function of stomata in plants?
To allow gas exchange and regulate water loss
Stomata are small openings on the surfaces of leaves.
What is the nucleus of a cell?
The centrally located, spherical structure that contains genetic material
The nucleus is surrounded by a nuclear membrane.
What do guard cells do?
Regulate the opening and closing of stomata
Guard cells control gas exchange and water loss in plants.
What is the primary substance absorbed by plant roots?
Water and minerals
Roots take up essential nutrients from the soil.
What are the main components of the cell wall in plants?
Cellulose and other polysaccharides
The cell wall provides structural support to plant cells.
What is the term for the process by which plants convert light energy into chemical energy?
Photosynthesis
True or False: All plants are autotrophic.
True
What is the function of the cell membrane?
To protect the cell and regulate the movement of substances in and out
The cell membrane is selectively permeable.
Fill in the blank: The process of nutrient absorption in plants primarily occurs through _______.
roots
What is the role of minerals in plant nutrition?
To support various physiological functions and growth
Minerals are essential for enzyme function and structural integrity.
What is the significance of the chloroplast in plant cells?
Site of photosynthesis
Chloroplasts contain chlorophyll and other pigments.
