Nucleus Ribosomes Cytoplasm Cell Wall Mitochondria Vacuole Chloroplast Cell membrane

Nucleus Nucleus is the control center of the cell. It is a membrane bound structure which contains the hereditary material of the cell - the DNA. It is most important part of an object, movement, or group, forming the basis for its activity and growth. Click above arrow to go back

Ribosomes Ribosomes are structures that assemble proteins. It is a minute particle consisting of RNA and associated proteins, found in large numbers in the cytoplasm of living cells. They bind messenger RNA and transfer RNA to synthesize polypeptides and proteins Click above arrow to go back

Cytoplasm Cytoplasm is a thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts, and proteins. In eukaryotic cells, the cytoplasm includes all of the material inside the cell and outside of the nucleus. Click above arrow to go back

Cell Wall The cell wall a rigid layer of polysaccharides lying outside the plasma membrane of the cells of plants, fungi, and bacteria. In the algae and higher plants, it consists mainly of cellulose. Click above arrow to go back

Mitochondria Mitochondria is an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to form layers (cristae). Click above arrow to go back

Vacuole Vacuoles are storage bubbles found in cells. They are found in both animal and plant cells but are much larger in plant cells. Vacuoles might store food or any variety of nutrients a cell might need to survive. They can even store waste products so the rest of the cell is protected from contamination.

Chloroplasts Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis. Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant. Click above arrow to go back

Cell Membrane The cell membrane is the semipermeable membrane surrounding the cytoplasm of a cell. Click above arrow to go back

The cell membrane is also known as the _______ membrane. A. Pleural B. Plasma C. Placental Click above arrow to go back

The cell membrane is also known as the plasma membrane. It protects the plant cell and the animal cell & regulates the entry and exit of substances, namely ions and solutes. Click above arrow to go back

The nucleus is the most important part of the plant cell and the animal cell, and contains large amounts of DNA (Deoxyribonucleic acid). It controls and coordinates all the activities and functions of the cell. Click above arrow to go back

Ribosomes are found.. A. only in the nucleus B. in the cytoplasm C. only in eukaryotic cells

Click above arrow to go forward

Ribosomes are synthesized in the nucleolus but are found predominantly in the cytoplasm, singly or in chains. Click above arrow to go back
