Prokaryotic cells do not have membrane bound organelles. Eukaryotic cells do have membrane bound organelles. The membrane controls movement in and out of the cell. ... The cytoplasm fills the space between the nucleus and the cell membrane.
D) A & B
it protects the seed against any damage or harmful weather conditions and also helps in dispersal of the seed through different means.
Answer:
The statement C that says ''is derived from the inner cell mass'' is false.
Explanation:
The trophoblast is a structure composed of a set of cells (cytotrophoblast and syncytiotrophoblast), which are shaping the outer layer surrounding a blastocyst, during the earliest stages of embryonic development that mammals pass.
The trophoblast provides nutritive molecules to the developing embryo and facilitates its implantation to the uterine wall due to its ability to erode the tissues of the uterus, that is, it is responsible for making it possible for the embryo to be implanted in the uterine endometrium. Thus, the blast can join the cavity formed by the uterine wall, where it will absorb nutrients from the fluid from the mother.
During the third week, embryonic development includes the development of the trophoblast. At the beginning, the primary villi are formed by the internal cytotrophoblast which is surrounded by the outer layer of syncytiotrophoblast. Then, the cells found in the embryonic mesoderm are directed to the primary villous in the third week of gestation and when it ends, the mesodermal cells begin to be singled out to form blood vessel cells.

How is photosynthesis similar to cellular respiration? How do they differ?
Similarities Between Photosynthesis And Cellular Respiration
Similarities ...
→ Both involve in production of energy
→ Both involve the exchange of gases
→ Both the process takes place in cell organelle which was considered as endosymbiotic organism. They are chloroplast and Mitochondria, Photosynthesis takes place in Chloroplast where as respiration takes place in mitochondria.
→ At critical condition both have alternate pathway.
Differences...
→Photosynthesis takes place in chloroplast, where as respiration takes place in mitochondria.
→Photosynthesis involve production of carbohydrate and respiration involve breaking of carbohydrate.
→ Photosynthesis occur only during presence of sunlight where as respiration occurs all the time.
→ In photosynthesis process Oxygen is released where as in respiration Oxygen is utilised.
These are the main differences between Photosynthesis and respiration.
What city ru talking about not enough information lol lol lol
