Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...
The leukoplast (most commonly spelled leucoplast) is a non-pigemented plastid (i.e. chloroplast) and typically only occurs in non-photosynthetic tissues - which is slightly problematic since this cell also has chloroplasts (and it should since they are a defining character of a "plant cell") - and should probably be removed for simplicity and ...
All green parts of a plant contain chloroplasts as the color comes from the chlorophyll. [11] The plant cells which contain chloroplasts are usually parenchyma cells, though chloroplasts can also be found in collenchyma tissue. [181] A plant cell which contains chloroplasts is known as a chlorenchyma cell. A typical chlorenchyma cell of a land ...
Chloroplasts in leaf cells of the moss Mnium stellare. Plant anatomy or phytotomy is the general term for the study of the internal structure of plants.Originally, it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure.
Some eukaryotic cells (plant cells and fungal cells) also have a cell wall. Inside the cell is the cytoplasmic region that contains the genome (DNA), ribosomes and various sorts of inclusions. [2] The genetic material is freely found in the cytoplasm. Prokaryotes can carry extrachromosomal DNA elements called plasmids, which are usually circular.
This is a diagram of cell elongation in a plant. In sum, the acidity within the cell wall as a result of a high proton concentration in the cell wall. As a result,the cell wall becomes more flexible so that when water comes into the plant vacuole, the plant cell will elongate. This image shows the development of a normal plant.

Sclerenchyma is the tissue which makes the plant hard and stiff. Sclerenchyma is the supporting tissue in plants. Two types of sclerenchyma cells exist: fibers cellular and sclereids. Their cell walls consist of cellulose, hemicellulose, and lignin. Sclerenchyma cells are the principal supporting cells in plant tissues that have ceased elongation.
