4. Cell Membrane
5. Pseudopodia
1. Nucleus
2. Plastids
3. Genes
Answers
Answer:
Hope this helps !!
Explanation:
Cell Membrane:
It separates the content of cell from their external environment. It allows the materials from surrounding to enter and exit the cell. It also allows the materials from cell to exit outside. It controls the entry and exit of materials in nd out of cell and hence it is called selectively permeable membrane.
Pseudopodia:
The pseudopods are used in movement and as a tool to capture prey.
Nucleus:
The nucleus has 2 primary functions: It is responsible for storing the cell's hereditary material or the DNA. It is responsible for coordinating many of the important cellular activities such as protein synthesis, cell division, growth and a host of other important functions.
Plastids:
Plastids are responsible for manufacturing and storing of food. These often contain pigments that are used in photosynthesis and different types of pigments that can change the color of the cell.
Genes:
They give instructions for a living being to make molecules called proteins.
Answer:
5.Pseudopodia are an example of blunt transient processes employed by cells such as amoeba or the neutrophil leucocyte for locomotion and the uptake of food particles and /or other extraneous matter.
4.The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
3.Genes are a set of instructions that determine what the organism is like, its appearance, how it survives, and how it behaves in its environment. Genes are made of a substance called deoxyribonucleic acid, or DNA. They give instructions for a living being to make molecules called protein
2.Plastids are responsible for photosynthesis, storage of products like starch, and for the synthesis of many classes of molecules such as fatty acids and terpenes, which are needed as cellular building blocks and/or for the function of the plant.
1.The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus.
