4 ) Name the plastid involved in the storage of food material in the plant cell.
5 ) Name the cell organelle found in plant cell but not in animal cell.
6 ) Which structure take part in animal cell division ?
Answers
Answer:
Theodor Schwann
1.The classical cell theory was proposed by Theodor Schwann in 1839.
2.Nucleus. ... Known as the cell's “command center,” the nucleus is a large organelle that stores the cell's DNA (deoxyribonucleic acid). The nucleus controls all of the cell's activities, such as growth and metabolism, using the DNA's genetic information.
3.Ribosomes are the protein factories of the cell. Composed of two subunits, they can be found floating freely in the cell's cytoplasm or embedded within the endoplasmic reticulum
4.Plastids are organelles involved in the synthesis and storage of food. They are found within the cells of photosynthetic eukaryotes. In plants, plastids may develop into these forms: (1) chloroplasts, (2) chromoplasts, (3) gerontoplasts, and (4) leucoplasts.
5.The plant cell has a cell wall, chloroplasts, plastids, and a central vacuole—structures not found in animal cells
6. Centrioles
Every animal-like cell has two small organelles called centrioles. They are there to help the cell when it comes time to divide. They are put to work in both the process of mitosis and the process of meiosis.
