How many chloroplast in a plant cell
WebThe plant cell must be able to sense these adverse conditions and then coordinate an appropriate response to maintain robust photosynthesis. Keeping photosynthesis active requires coordination of signaling and metabolism between the chloroplast (green circle) and other cellular compartments (dotted lines). WebThe chloroplast is involved in both stages of photosynthesis. The light reactions take place in the thylakoid. There, water (H 2 O) is oxidized, and oxygen (O 2) is released. The …

WebIntron excision is important in the nucleus of animal and plant cells, as well as cellular organelles like plant chloroplasts which have their own gene expression machinery. Introns can be removed by three mechanisms: 1) the nuclear spliceosome, 2) self-excision, or 3) maturase enzymes. MatK is the only maturase encoded in the chloroplast of ... WebMar 27, 2024 · Chloroplasts are roughly 1–2 μm (1 μm = 0.001 mm) thick and 5–7 μm in diameter. They are enclosed in a chloroplast envelope, which consists of a double membrane with outer and inner layers, between which is a gap called the intermembrane …
