Plants acquire varied colours because of pigments present in plastids called chromoplasts. These pigments include carotenoids and others that give red, yellow and orange colours. The colours help attract pollinators and animals for seed dispersal. Chlorophyll gives green colour, while other pigmentsRead more

Vacuoles are membrane-bound organelles that store water, minerals, sugars and waste products. In plant cells, a large central vacuole maintains turgor pressure, which keeps the cell firm and supports the plant structure. In animal cells, vacuoles are smaller and help in temporary storage and transpoRead more

Yes, white flowers may contain pigments, but they do not have pigments that absorb visible light strongly. Instead, they reflect most of the light, giving a white appearance. In some cases, the absence of pigments also results in white colour. Thus, white flowers may either lack pigments or containRead more
Yes, white flowers may contain pigments, but they do not have pigments that absorb visible light strongly. Instead, they reflect most of the light, giving a white appearance. In some cases, the absence of pigments also results in white colour. Thus, white flowers may either lack pigments or contain colourless ones.

A well-labelled diagram of a cell should include a dark, round nucleus at the centre, endoplasmic reticulum as a network extending from it and rod-shaped mitochondria and chloroplasts in plant cells. Other parts like cell membrane, cytoplasm and vacuole should also be shown clearly. Proper labellingRead more
