The green color of plants are caused by plastid. Leucoplasts are non-pigmented in contrast to other plastids. They are usually found in the cells of the plant parts where usually sunlight does not reach; for example’ root, ovaries and embryo. As a result, the plant’s roots are colorless.
Because of their hardness, sclerites are called stone cells.
The aggregation of cells that are alike in origin and structure and collectively perform a special function is called tissue. Plant tissue can be grouped into two types: simple tissue (parenchyma, collenchyma and sclerenchyma) and complex tissue (xylem, phloem).
Cells that contain a well-organized nucleus within a nuclear membrane, well-organized chromosomes with DNA, histone protein are known as the eukaryotic cells.
Plastids are transmitted from generation to generation through a unique mode of inheritance. These plastids are called transmitted plastids for any given organism at any given time.
Intercalated discs are certain features that are only available in cardiac muscles.
ATP (Adenosine triphosphate) is known as ‘biological currency’ or energy coin, where energy is stored and can be used whenever cell demands.
The paternal and maternal character that is exposed in the first filial generation is known as the dominant character.
