The middle section immediately behind the head is packed with . Although an egg can give rise to every cell type in the adult organism, it is itself a highly specialized cell, uniquely equipped for the single function of generating a new individual. Cell Specialization: All living organisms are composed of one or more cells – this statement is probably one of the most important principles of the Cell Theory by Theodor Schwann and Matthias Schleiden.. Start studying cell specialisation. Start studying Cell specialisation.. The ovum (egg cell) in the animals and the plants. Cells: Cells are the basic units of all life that make up tissues, organs, and organ systems. About the Owner. Contains haemoglobin which picks up oxygen. From this first cell, it must be possible for all other cell types to develop. the nucleus contains genetic information about the mother. Edit. That cell is not specialised. there is a large store of food in the vacuoles. 221 times. This is the only part of the sperm cell that enters into the egg cell. Log in Sign up. Students should be able to, when provided with appropriate information, explain how the structure of different types of cell relate to their function in a tissue, an organ or organ system, or the whole organism. cell name: sperm cell cell function : to fertilise egg cell Both animal cells and plant cells share the same 3 features. Given that all cells in our body have developed from one single cell, “the egg or ovum fertilised by one spermatozoon”, all cells are identical, that is, they contain exactly the same instructions. Notes/Highlights. Thin cell wall. Show Hide Resources . Learn vocabulary, terms, and more with flashcards, games, and other study tools. Show Hide Details , . In this case, the embryonic stem cells, undergo specialisation to give the many different cells and tissues of the body. Save. Nerve cell. The ovary produces egg cells which is the gametes. When a sperm and an egg fuse at conception, the very first cell of a new human is created. Egg cells differ greatly from sperm in their structure. GCSE BIOLOGY REVISION: CELL SPECIALISATION . provides nutrients for growing embryo. 30 seconds . 1. ATS GCSE Biology - Cell Specialisation DRAFT. Cells can become specialized to perform a particular function within an organism, usually as part of a larger tissue consisting of many of the same cells working together for example muscle cells. Learn vocabulary, terms, and more with flashcards, games, and other study tools. a) Control the cell b) Trap sunlight for photosynthesis c) Give support d) Colour the cell green 6) Which cell carries oxygen around the body? In adults, stem cells are specialized to replace cells that are worn out in the bone marrow, brain, heart and blood. haploid nucleus, single set of unpaired chromosomes. This makes sense given that the body of multi-cellular organisms are made up of them but are not all identical. Red blood cell 5) What does chlorophyll do? For this reason, it is a key part of the spermatozoon, as it is the one that unites with the egg's nucleus to form a 46-chromosome cell called zygote.

These cells display specialised features that make them suited to carry out their specific function. Tell us. Some people call it specialisation, some specialization. Now we have established the general features of both animal and plant cells we must also remember that many cells do look different and this is because they have their own special jobs to do. 3 years ago. Why is cell specialisation important to multicellular organisams ... Metazoan cells, i.e., the cells in “true” multicellular organisms don’t just temporarily specialize, they permanently differentiate as the organism develops from a fertilized egg to an adult. Root Hair Cells. From this first cell, it must be possible for all other cell types to develop. This is rigid, so it gives the plant cell its shape. Given examples, descriptions, and illustrations, students will be able to describe the role of DNA, RNA, and environmental factors in cell differentiation. Search.
