Answer:
4-The four parts of the cell membrane are phospholipids, proteins, carbohydrates and cholesterol.
6-Protoplasm comprises the living part of the cell. It includes cytoplasm, nucleus and other organelles. Protoplasm is enclosed within the cell membrane, but itself is not a part of protoplasm
7-Golgi
9-Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique
11-The nucleus is one of the most prominent cellular organelles, yet surprisingly little is known about how it is formed, what determines its shape and what defines its size. As the nuclear envelope (NE) disassembles in each and every cell cycle in metazoans, the process of rebuilding the nucleus is crucial for proper development and cell proliferation. In this Commentary, we summarize what is known about the regulation of nuclear shape and size, and highlight recent findings that shed light on the process of building a nucleus, including new discoveries related to NE assembly and the relationship between the NE and the endoplasmic reticulum (ER). Throughout our discussion, we note interesting aspects of nuclear structure that have yet to be resolved. Finally, we present an idea – which we refer to as `the limited flat membrane hypothesis' – to explain the formation of a single nucleus that encompasses of all of the cell's chromosomes following mitosis.
12-DNA molecules
Inside its fully enclosed nuclear membrane, it contains the majority of the cell's genetic material. This material is organized as DNA molecules, along with a variety of proteins, to form chromosomes.
13-Centrioles
14-Centrosomes are composed of two centrioles arranged at right-angles to each other, and surrounded by a dense, highly structured mass of protein termed the pericentriolar material (PCM). The PCM contains proteins responsible for microtubule nucleation and anchoring including γ-tubulin, pericentrin and ninein.
