Cell organelles are specialized entities present inside a particular type of cell that performs a specific function. There are various cell organelles, out of which, some are common in most types of cells like cell membranes, nucleus, and cytoplasm. However, some organelles are specific to one p...
Structure of Plant cell Generally, plant cells are a lot bigger than animal cells, coming in more similar sizes and they are typically cubed or rectangular in shape. Plant cells also have structural organelles that are not found in the animals’ cells including the cell wall, vacuoles, plastids...
It is therefore assumed that there is a two-fold screw axis in the structure. In general this is valid, but there are special circumstances when such absences occur for a different reason. Thus, in a unit cell containing an asymmetric unit composed of two sub-units, the condition for the...
Arising from the upper portion of the uterus on each side are theFallopian tubes. These are channels that allow eggs from the ovaries to enter the uterus. The process of fertilizationof an egg by a sperm cell typically happens in the Fallopian tubes, and the fertilized egg moves into the ...
Here we present a neuronal wiring diagram of a whole brain containing 5 × 107 chemical synapses7 between 139,255 neurons reconstructed from an adult female Drosophila melanogaster8,9. The resource also incorporates annotations of cell classes and types, nerves, hemilineages and predictions of ...
Chloroplast- Site of Photosynthesis. Granum(Grana) - stacked thyalkoid membranes. Stroma- fluid matrix surrounding the thylakoids. Thylakoid- Membrane found in the chloroplast. Intercellular air space- gap between cells. Cell Wall- Rigid structure surrounding plant cells, not present in animal cells...
The stratum granulosum is composed of tightly compacted, flattened cells that help waterproof the skin. The stratum spinosum contains irregular shaped (spiny) cells that are several cell layers thick. Lastly, the stratum basale layer is made up of differentiation cells that are constantly dividing to...
