After germination, continued plant growth pushes first the shoot and then leaves through the soil. We would expect the emergent leaf cells to contain many _ for photosynthesis. Because the developing stem must support the plant, we would expect those cells to develop __.

Chloroplasts are certainly the most important organelles of plant cells and also of all living things since they allow photosynthesis, the source of all organic matter in the biosphere. The structure of the chloroplasts of higher plants is very homogeneous

2. The right answer is thickened cell walls.

Collenchyme is a support tissue for vascular plants. The cells are alive, not impregnated with suberin or lignin (like those of sclerenchyma for example), isodiametric or elongated; the primary wall remains cellulosic but is provided with uneven and elastic cellulosic thickening. It is found mainly in young organs (stem, leaf, root). In older organs, this tissue is stiffened by a change in the composition of the cell wall or undergoes sclerification via the lignification process.

After germination, continued plant growth pushes first the shoot and then leaves through the soil. We would expect the emergent leaf cells to contain many _____________ for photosynthesis. Because the developing stem must support the plant, we would expect those cells to develop ______________.
