Fwd: Plant Cell research






The Organelles of the Green Leaf Cell:
  • Nucleus
  • Cytoplasm
  • Cell membrane
  • Mitochondrion
  • Golgi Apparatus
  • Rough Endoplasmic Reticulum
  • Smooth Endoplasmic
  • Large Central Vacuole
  • Starch Grain
  • Cell Wall

Nucleus:
controls all activities in the cell— This organelle's function is important as the cell's processes need to be controlled it does that.

Cell membrane:
controls all movement of the substances into and out of the cell.—The cell membrane's function is important as certain things in the cell need to stay in, and others out. The cell membrane does that.

Golgi Apparatus:
where lipids and protein are stored and packed for secretion out of the cell. — The lipids and proteins need to be sent out of the cell, before that is done, a storage container is required. The Golgi Apparatus does that job.

Smooth Endoplasmic:
processes lipids, carbohydrates and other substances. — Lipids, carbohydrates and other substances need to be processed before they are used, and the smooth endoplasmic does that job.


Starch Grain:
stores the excess glucose produces during photosynthesis in the form of starch. — The plant will make extra glucose during photosynthesis, and it is useful later on when the plant does not have enough food. The excess glucose is stored away in the form of starch in the starch grain

Cytoplasm
Cellular activities takes place.— The cellular activities need somewhere to take place and the cytoplasm is that place

Large Central Vacuole
It is a water-filled volume enclosed by a membrane which maintains the cell's turgidity. It controls the movement of molecules.

Cell Wall
A cell wall is composed of cellulose and hemicellulose. It is fully permeable and allows all substances to pass through it. It gives shape and protects the mechanical support to the plant. — The cell wall give the cell structural support and thus makes it stronger as a whole

Rough Endoplasmic Reticulum
The endoplasmic reticulum (ER) is an Eukaryotic Organelle that forms an interconnected network of tubules, vesicles, and cisternal within cells. Rough endoplasmic reticulum processes proteins and they are studded with ribosomes.

Mitochondrion
It produces energy in the form of adenosine triphosphate (ATP) by breaking down food molecule glucose through the process of cellular respiration. Mitochondria are sometimes described as "cellular power plants" because they generate most of the cell's supply of ATP, used as a source of Chemical Energy. In addition to supplying cellular energy, mitochondria are involved in a range of other processes, such as signaling cellular differentiation, cell death, as well as the control of the cell cycle and cell growth.
