What are the vacuoles and vesicles?
Membrane-bound structures that serve to store nutrients, products of secretion, and fats, depending on the tissue type. In plants, the central vacuole stores water for the cell. In plant cells, when fluid enters the turgor pressure increases, making the cell firm or turgid. Vesicles transport substances throughout the cell.
A gel-like substance inside the cell membrane: Contains nutrients needed by cell to carry out life processes. Organelles are suspended in cytoplasm.
Cell membrane?
The cell wall, a protective barrier.
Membrane-bound sacs in the cell in which digestion can occur. Defend against bacteria, destruction of damages cell organelles
Control center of the cell, contains DNA
Site of photosynthesis, contain chlorophyll that produce a green colour.
Dense looking grandules formed of two parts. May be attached to the endoplasmic reticulum or free in the cytoplasm. Ribosomes are the sites where amino acid are assembled into proteins in the process of protein synthesis
Rod-like structures where reactions occur to convert chemical energy in sugar into energy the cell can use. *
* What is this process called?
Cellular respiration
Golgi Apparatus?
Composed of flat, disc-shaped sacs involved in secretion. The Golgi recives substance from endoplasmic reticulum and packages them for transport out of the cell.
