NEET BIOLOGY

Detailed explanation-1: -Like land plants, phytoplankton have chlorophyll to capture sunlight, and they use photosynthesis to turn it into chemical energy. They consume carbon dioxide, and release oxygen. All phytoplankton photosynthesize, but some get additional energy by consuming other organisms.

Detailed explanation-2: -Protists are single and multi-cellular organisms that are plant-like, animal-like, and fungi-like.

Detailed explanation-3: -Plant-like protists (AKA algae) are usually photosynthetic organisms, and most contain chloroplasts and/or chlorophyll.

Detailed explanation-4: -Like plants, fungi are autotrophs. Fungi cannot make their own food like plants can, since they do not have chloroplasts and cannot carry out photosynthesis. Fungi are more like animals because they are heterotrophs, as opposed to autotrophs, like plants, that make their own food.

Detailed explanation-5: -Diatoms are an enigma. Neither plant nor animal, they share biochemical features of both. Though simple single-celled algae, they are covered with elegant casings sculpted from silica.
