Chapter 10.3: Plant Processes Flashcards
- describe the relationship and understand the significance between photosynthesis and cellular respiration - know the balanced equations for photosynthesis and cellular respiration - use proportions to calculate the number of ATP or glucose molecules produced or broken down - explain how water and minerals move in vascular and nonvascular plants - understand and explain how plants respond to environmental changes
What do plants respond to in their environment?
Stimuli (examples; light, water, gravity and touch).
Growth towards or away from a stimulus is called a?
Tropism (examples; thigmo, gravi and phototropism).
Plants produce sugar through which process?
Photosynthesis.
Is glucose a type of fat, protein or carbohydrate?
Carbohydrate (sugars are types of carbs).
Name the two reactants required for cellular respiration.
Oxygen and glucose.
What cell organelle does respiration take place in?
Mitochondria.
Photosynthesis occurs in which plant cell organelles?
Chloroplasts.
What green pigment is important for the process of photosynthesis?
Chlorophyll.
The bottom of leaves have small pores or holes, what are these called?
Stomata.
If a plant grows towards a stimulus is this positive or negative tropism?
Positive tropism (move towards).
If a plant grows away from a stimulus is this positive or negative tropism?
Negative tropism (away from a stimulus).
Leaves show positive phototropism, true or false?
True, leaves grow towards sunlight.
If a root grows away from a rock is it showing positive or negative thigmotropism?
Negative thigmotropism, as it does not want to touch the rock.
Roots show negative gravitropism, true or false?
False, the grow towards the ground, this is positive gravitropism.
Name two ways that water and nutrients move in non vascular plants.
Osmosis and diffusion.
