the cell is the the basic structural unit
the cell is the functional unit
Robert Hooke was the first scientist who, in 1665, observed thin slices of cork through his self - designed microscope
living organism can be classified into two categories : unicellular and multicellular.
organism consist of a single cell
organism made up of many cells
the shape of cell may be oval, spherical, cuboidal, fibre like or polygonal. These differences in shapes are due to their location and function in the tissue.
the smallest cell pplo ( Pleuro pneumonia - like organism ), also called mycoplasma, is about 0.1 micron.
also called plasma membrane. Controls the entry and exit of substances.
also called protoplasm. It is the gel-like material. It acts as a ground substance for all cell activities.
The cells of plants, fungi, and bacteria have an additional outer covering called the cell wall. It provides rigidity and protection to cell. It also gives a definite shape, size and support to the cell.
It generally lies in the centre of the cell, but sometimes it also occupies the perioheral positions and it also controls all the activities of the cell. The nucleus is a dense structure bound by a nuclear membrane. The protoplasm of the nucleus is called nucleoplasm. It has a thread like network called chromatin. When chromatin condenses to form thiker, thread like structures called chromosomes.
The green coloured plastids are called chloroplasts. The plastids, associated with different coloured parts of the plants are called chromoplasts. Plants also contain some colourless plastids called leucoplasts.
rod shaped spherical structures. They have cellular respiration for generation of energy. Also called powerhouse of cell.
It is network of membranes. It provides channels for transport of materials.
It is studied with ribosomes. It helps in sythesis of proteins.
It does not have ribosomes. It helps in synthesis pf fats.
They are sac like structures. They do processing and packaging of materials by the cells.
It is as empty space in the cytoplasm. It is large in plants cells. It stores excess of water and waste products. In Amoeba, food materials are held in its food vacuoles for digestion.
They are tiny granuals in the cytoplasm and on rough ER. They help in protein synthesis.
They are small extenctions on their cell membrane. They help in locomotion and collection of food. Like Paramoecium, have numerous cilia while Euglena has a single flagellum.
