Plant Kingdom

Answer

Plant kingdom comprises multicellular, autotrophic organisms. It includes major groups such as algae, bryophytes, pteridophytes, gymnosperms, and angiosperms.

Answer

Plants probably arose from the algal division Chlorophyta. Green algae are especially close to land plants in their pigments, food storage, and cell wall composition.

Answer

Cyanobacteria, also called blue-green algae, are not algae any more. They are placed in Monera because they are prokaryotic, unlike true algae which are eukaryotic.

Answer

Algae are chlorophyll-containing thalloid autotrophic plants of the simplest type. They lack true roots, stems, leaves, or leaf-like organs and commonly live in aquatic habitats.

Answer

Algae are divided into three major divisions: Rhodophyceae, Phaeophyceae, and Chlorophyceae. These groups are mainly distinguished by their pigments, storage food, and other structural features.

Answer

Red algae contain the water-soluble red pigment r-phycoerythrin, which masks the green colour of chlorophyll a. This pigment also helps them live at greater depths in the ocean than other algal groups…

Answer

Rhodophyceae are mostly marine algae with no flagellated cells at any stage of the life cycle. Their reserve food is floridean starch, and their pigments include chlorophyll a and d, carotenes, xantho…

Answer

Common examples include Batrachospermum, Polysiphonia, Porphyra, Gracilaria, and Gelidium. Porphyra and Rhodymenia are used as food, agar is obtained from Gelidium, Gracilaria, Chondrus, and Gigartina…
