When guard cells take up water, their Turgor pressure increases and the stomatal pores open. One of the distinctive aspects of a plant cell is the presence of a cell wall outside the cell membrane. Guard Cells (Plants) The guard cell “guards” the stomata (plants air hole) by swelling and shrinking to control the rate of transpiration while still allowing enough air to enter. They possess a protein called hemoglobin that is responsible for their oxygen-carrying capacity. These cells undergo specialization in order to perform all functions that are necessary to support life. Neurons can be up to one meter in length depending on where they are present. These are the male reproductive cells. Asked 2 … Therefore, in order to grow, an organism must increase the number of cells it is made up from. In addition, there is a number of specialized types of plant cells that are found only in vascular plants. Cells, Specialized Types The specialized cell types found in plant stems, leaves, roots, flowers, and fruits are organized into three tissue systems: the ground tissue system, the dermal tissue system, and the vascular tissue system. These cells have a hair-like outgrowth on the cell surface. Log in for more information. However, the genetic makeup of every cell in an organism’s body is the same.

These cells display specialised features that make them suited to carry out their specific function. They possess proteins like myosin and actin that aid in the contraction of cells. In plants, the undifferentiated meristematic tissues are found in the apical tips and allow the plant to grow throughout its lifetime. Dendrites are the cellular extensions that receive impulses, and axons are long cable-like projections that transmit the impulse to the next neurons. Plant cells are eukaryotic cells or cells with a membrane-bound nucleus. Cell Specialisation – Animals Plant cells are a type of eukaryotic cell that are found in organisms of the Plant Kingdom. muscle cells). Groups of special-pecialized cells perform specialized functions in multicellular organisms. The mid piece consists of centrioles and mitochondria wrapped around the axial filament of the flagellum. Contains cell sap and when full pushes the cell membrane against the cell wall, providing support. For example: Bulbs are underground buds with the stem reduced to a small knob on which fleshy storage leaves are clustered (e.g. Phloem, also called bast, tissues in plants that conduct foods made in the leaves to all other parts of the plant. The neurons consist of the soma, dendrites, and axons. A selectively permeable boundary surrounding the cell which allows some substances to enter and leave the cell while preventing others.
