the covering of cell present only in plant cell is _
Answers
Answer: The Cell Wall
Answer:
The covering of cells present only in the plant cell is called the cell membrane
Explanation:
A plant cell is the basic unit of all plants. Plant cells are eukaryotic cells. Unlike animal cells, plant cells have a cell wall surrounding the cell membrane. Plant cell walls are made up of cellulose. plant cells can be distinguished from most other cells by the presence of chloroplast.
A chloroplast is a type of plastid that serves the site of photosynthesis, the process that which the energy from the sun is converted into chemical energy.
Another important feature of many plants cell is the presence of one or more large vacuoles. Vacuoles are storage organelles.
PLANT CELL STRUCTURE
- cell wall: rigid layer composed of cellulose, glycoproteins, lignin, pectin, and hemicellulose.
- cell membrane: It is the semi-permeable membrane that is present within the cell wall.
- Nucleus: Membrane-bound structure, present in the eukaryotic cells.
- plastids: Membrane-bound organelles that have their DNA.
- central vacuoles: It occupies around 30% of the cell volume in a mature plant cell.
- Golgi apparatus: They are found in all eukaryotic cells.
- Ribosomes: They are the smallest membrane-bound organelles that comprise RNA and protein.
- Mitochondria: They are the double-membraned organelles found in the cytoplasm.
- Lysosome: Lysosomes are called suicide bags as they hold digestive enzymes
TYPES OF PLANT CELL
1) Collenchyma cells: They are hard or rigid cells.
2)Sclerenchyma cells: These cells are more rigid when compared to the collenchyma cells.
3)Parenchyma cells: They are the living cells of the plant, which are involved in the production of leaves.
4)Xylem cells: Transport cells in vascular plants. They help in the transport of water and minerals from the roots to the leaves.
5)Phloem cells: Other transport cells in vascular plants. they help to transport food prepared by the leaves to different parts of the plants
