Cells
indiasmith
Cell membrane
- the semipermeable membrane surrounding the cytoplasm of a cell.
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
Cytoplasm
- The material or protoplasm within a living cell, excluding the nucleus.
Nucleus
- The central and most important part of an object, movement, or group, forming the basis for its activity and growth.
Nuclear memebrane
- A nuclear membrane, also known as the nuclear envelope, nucleolemma or karyotheca, is the double lipid bilayer membrane which surrounds the genetic material and nucleolus in eukaryotic cells.
Nucleololus
A small dense spherical structure in the nucleus of a cell during interphase.
Centrioles
A minute cylindrical organelle near the nucleus in animal cells.
Occurring in pairs and involved in the development of spindle fibers in cell division.
Chromatin
Material of which the chromosomes of organisms other than bacteria (eukaryotic) are composed. It consists of protein, RNA, and DNA.
Ribosomes
- Ribosomes are protein builders or protein synthesizers
Gologi apparatus
Endoplasmic reticulum
Mitochchondria
- An organelle found in large numbers in most cells
It has a double membrane, the inner layer being folded inward to form layers.
chloroplast
- A plastid that contains chlorophyll and in which photosynthesis takes place
Lysosomes
- an organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane.
Peroxisomes
A small organelle that is present in the cytoplasm of many cells and that contains the reducing enzyme catalase and usually some oxidases.
Vacuole
a sA A small cavity or space in tissue, especially in nervous tissue as the result of disease.
Orig
cytoskeleton
- A microscopic network of protein filaments and tubules in the cytoplasm of many living cells, giving them shape and coherence.
