Answer:
1 .The leaves are only a small part of the plant and must produce enough energy-rich sugars to support all non-green parts like roots or flowers --TRUE.
2.Only when overall photosynthetic activity is greater than overall respiration activity of the whole plant can the plant accumulate biomass and grow--TRUE.
3.Sugar produced in photosynthesis must support the plant’s energy needs both day and night TRUE.
4. In trees that drop their leaves over the winter, some sugar produced in one year is stored in stems or roots and fuels the production of new leaves in the next year TRUE.
The statement that is FALSE is
Leaves perform more photosynthesis than respiration because they don’t have mitochondria.
Explanation:
The statement that is FALSE is
Leaves perform more photosynthesis than respiration because they don’t have mitochondria and it is false because leaves contain both mitochondria and chloroplast.
The plants leaves have chloroplast, an organelles that house the chlorophyll which help its to photosynthesized. Plants also require ATP to carry out cellular activities and need oxygen to breakdown sugars produced from photosynthesis to produce ATP, because of this, they need mitochondria to achieve this and that is why they have mitochondria.
In the night, when there is no sunlight, plants perform respiration, they use oxygen to break the sugars they produced in order to produce ATP.
