The amoeba “breathes” using this membrane – oxygen gas from the water passes in to the amoeba through the cell membrane and carbon dioxide gas leaves through it. Amoebas can form temporary extensions of their cytoplasm known as pseudopodia or "false feet" which can be used for locomotion or capturing food. splicing of the cell into 2 parts), the cell quickly dies. Size, shape and number of these depend on the size, shape and number of food materials. Ans. Let us discuss these parts and their functions in more detail . Amoeba changes its shape using pseudopodia that help in their movement. The fruit forms around the seed. 12. Waste gas, carbon dioxide, passes through the cell membrane into the water outside the cell. The Nucleus and Its Parts The nucleus is composed of many parts that help it function properly within the cell. Office … 1. (B) Vacuoles: There are several types of vacuoles in Amoeba. The eyes of a fish have large round pupils which do not vary in size. It also discharges carbon dioxide and excretory materials through the membrane. a)  Food vacuoles store the food material.

It lacks a definite body shape because it changes its shape by producing the pseudopodia every moment. Ans. Chloroplasts are the green plastids which act as photosynthetic apparatus. Sporulation: It is the inactive phase of reproduction during which the nucleus of amoeba undergoes multiple divisions to form numerous spores. These are unstable outgrowths of the body and disappear soon. Moreover, as Amoeba's shape is changeable, its body cannot be divided into two similar parts. Amoebae do not form a single taxonomic group; instead, they are found in every major lineage of eukaryotic organisms.

Nucleus: At the middle of the endoplasm the translucent round body seen isthe nucleus. Nucleus conducts the functions of the Cell body. Frequent change in the density of the plasmagel and plasmasol helps in producing pseudopodia. Their role is to hold the strings down precisely in the position they are supposed to be. This mode of nutrition in amoeba is called holozoic nutrition where the food particles are engulfed to form a vacuole around it. They are able to encase food particles into small vacuoles and digest them. Regeneration: A part of the amoeba’s body having a fragment of its nucleus develops into a completely new organism. The parts that make up the nucleus include the nuclear envelope, nucleolus, and chromosomes/ chromatin. It helps to maintain the shape of the body.
