biology 3 revenge of the sith

Nucleus

Referred to as the brain of the cell, it controls all metabolic activities that carries on within a cell.

Cell membrane

Provides protection and it is selectively permeable in nature since it has the ability to control what enters and exits the cell

Cytoplasm

Clear thick fluid that contains organelles

Endoplasmic reticulum

Network of tubes, sacs and membranes responsible for transporting materials from one part of the cells to another

Smooth Endoplasmic reticulum

Storage for fats, lipids, and carbohydrates

Rough endoplasmic reticulum

Where ribosomes are located

Ribosomes

Tiny spherical structures that help make proteins. It can be found in the cytoplasm attached to the ER. site of protein synthesis

Mitochondria

Powerhouse of the cell. Where respiration takes place. Produces Adenosine triphosphate

Glycolysis

Process of mitochondrian respiration

Golgi apparatus

Numerous layers which form a sac like structure. It function includes electron transport chain protein packaging and its distance to other parts to the cell.

Centrioles

Releases spindle-like formations that attach to chromosomes during cell division

Vacuole

It acts as a storage for food, water, waste, and minerals

Lysosomes

Small structures that contain enzymes which are needed in digestion. It is also called the suicide sac. Contains hydrolithic enzymes (HCl)

Cytoskeleton

serves as the bones and muscle of the cell. It holds the cell wall and organelles in place.

Cell wall

Non living structure that surrounds a plant cell. It is made up of tough fiber called cellulose

Cilia and flagella

Locomotory appendages found in the exterior of the cell

Chloroplast

Contains the green pigment called chlorophyll used for photosynthesis

Prokaryotic

Lack of a nucleus, uses a nucleois which is a region of coiled up DNA. The nucleoid is suspended in cytoplasm with the rest of the cellular organisms.

Eukaryotic

DNA is contained in a nucleus, which separates the DNA from cytoplasm. Usually found in multicellular organisms.

Cartilage cells/Chondrocytes

Similar to bone cells but the surrounding materials is loose and flexible compared to those of bone cells.

Bone cells/osteocytes

Bound by calcium and phosphate material. Toughest cells in the body.

Nerve cells

Many branches are their ends. They are found in the brain and spinal cord.

Epithelial cells

These cells for the outer layers of all organs and are present in skin and scalp

Muscle cells

These cells are mostly long, large and, the ability to contract and relax, providing movements.

Secretory cells

These cells as the name indicates are secretory in nature. Found in all secretory organs.

Adipose cells

fat cells, reduces friction to the body.

Sperm cells

Present only in males, haploids, and contains an enzyme called hyaluronidase.

Blood cells

These cells are mobile and never stay in one place.

Pancreatic cells

Also known as the islet of Langerhans cell

Oocytes

Egg cells located in the uterus

Rod and cones

Captures light and colors to be converted into images. Located in the eye.
