How do eukaryotic plant and animal cells differ from one another?
Ber [7]

Answer:

The eukaryotic plant animal cells are differ having some cell organelles in it.

Explanation:

The first difference is the cell wall, which is present in all eukaryotic plants. It gives shape and rigidity to the plants. But all the animal cell the outer covering is cell membrane. They lack cell wall.

All the plant cell have chlorophyll pigment. It helps them to photosynthesis. In animal cell, chlorophyll molecule are absent. So they depend on plants for their food.

The eukaryotic plant cell more space is occupied by the vacuoles. It stores food and water for the plants. However, animal cells have no vacuole or if present, it is very small in size.

All animal cells have lysosomes, which help in digestion of various materials in the cell. Plants does not contain lysosomes.

Besides this organelles all other structure of plant and animals are similar. They both have nucleus, DNA, cytoplasm, mitochondria, etc.

Match the functional groups with their structures:
evablogger [386]
The true answer of your question is :

OH : HYDROXYL GROUP

NH2 : AMINO GROUP

CH3 : METHYL GROUP ( but in rather broader terms, that functional group of formula CnH2n+1 where n is an integer is called ALKYL GROUP where by substituting n by 1,2,3... we obtain methyl for n = 1, ethyl for n = 2, and propyl for n = 3 )

COOH : CARBOXYL GROUP is the correct answer since carbonyl is characterized by the presence of functional group C=O in general the formula of the compound would be
R-C=O-R’ where R and R’ are alkyl groups like methyl for example. However the carboxyl group could be thought of as a summation of carbonyl + hydroxyl ( CO + OH ) resulting thus in COOH.

I hope you’ll understand everything, anyway if not i’m always here to help. ♥️
