Answer:
The lipid bilayer.
Explanation:
It is a thin polar membrane made of two layers of lipid molecules. These membranes are flat sheets that form a continuous barrier around all cells.
Answer:
Z
Explanation:
The first stage of cellular respiration is called GLYCOLYSIS, where glucose is broken down into pyruvate. Because glycolysis occurs irrespective of whether there is oxygen or not, it occurs in all organisms. Hence, glycolysis occurs in the CYTOPLASM of their cell.
In this question, a diagram was given as an attachment. In the diagram, letters W, X, Y amd Z are used to represent organelles in the cell. Letter Z represents the cytoplasm, hence, the first stage of cellular respiration takes place in Z.
That process is known as Respiration in which oxygen get exchanged from the carbon dioxide by alveoli...
Answer:
Explanation:
Connective tissue serves to 'connect' or 'bind' the cells of other tissues in the body and gives them rigidity and support. Areolar connective tissue is of two types - white fibres (made of collagen) and yellow fibres (made of elastin).Tendon is made up of white fibres and connects muscles to bones
The cytoplasm is a fluid substance that fills every living cell which is enclosed by the cell membrane. This substance is mainly composed of water and proteins.
The functions that take place within the eukaryotic cytoplasm are diverse:
- Location for most metabolic pathways. Except for the metabolic pahtways in cell nucleus and cytoplasmatic organelles, all metabolic functions (e.g., synthesis of biomolecules, growth, etc) occur in the cytoplasm. The cytoplasm contain enzymes (i.e., proteins) to carry out different chemical reactions.
- Location for organelles that house many of the metabolic pathways for the cell. For example, the synthesis of ATP (the energy coin of the cells) is carried out in the mitochondria, which are organelles found in the cytoplasm.
- Location for the cytoskeleton that gives integrity to the cell. The cytoplasm contains all of the three types of filaments of the cytoskeleton (i.e., microtubules, actin filaments, and intermediate filaments) which provides structural support to the cells.
On the other hand, in plant cells, the cell wall is located outside the cell membrane.
