please help me guys

Answer:
I dont know the answers for all but i will write the ones i know
Explanation:
1-the tissues in plant and animals are not same
2-in multicellular respiration the work is divided bettween cells.
3-Meristematic tissue consist of actively dividing cells this is found in regions such as the tips of stems or roots and lead to increase in length and thickness of the plant this cells are spherical oval polygonal and rectangular and have thin cells walls.
4-Growth in plants is restricted to certain regions, because the dividing cells or meristematic cells are localised and not distributed throughout the plant body. The growth due to meristematic cells occurs by an increase in number of cells and not by increase in volume of existing cells.
Answer:
i dont know all the answers but i will give some answers that i know.
Explanation:
(1)tissues are not same in plants and animals
(2)In multicellular oraganisms group of cells called tissues together perform all the functions
(3)Meristamatic tissues are a dividing tissues.It divides upon different climatic conditions.After it divides it losses the dividing ability.It divides into a permanent tissues.Three types of meristamatic tissues are apical,lateral and intercalary meristems.
Cells of these tissues are very active ,dense cytoplasm,lack vacoules,permnaent nuclie.
(4)because the growth of plants depend upon climatic conditions.
(5)apical meristem helps the plants to increase their length.when it loses the dividing ability the length of the plants will be stopped
(6)dont know
(7)dont know
(8)vacoules are lack in meristamatic tissues because it is a dividing tissue.so if there is any presence of vacoule it cant divide because of the rigidity of vacoules.
(9) maybe no
(10)meristamatic tissues are a dividing tissues . it divides into a permanent tissue. after it divided it losese the dividing ability.lack of vacoule in mewristamatic tissue but it is found in permanent tissue.
classification of meristamatic tissue; APICAL,LATERAL,INTERCALARY.
classification of permanent tissue;
SIMPLE PERMANENT AND COMPLEX PERMANENT
(11)tis answer is same as the answert of5 and 10
(12)three simple permanent tissues are
- parenchyma =it stores food.
- collenchyma=it gives flexibility.
schlerenchyma=it contains lignin and it give strong to plants
(13) parenchymas cellwall is very thin
collenchymas cellwall is cornerly thickened
schlerenchymas cellwall is fully thickened
(14)parenchyma
(15)maybe chlorophyll
(16) because these cells are tightly packed so there is no intercellular spaces.
(17)sorry dont know
(18)sclerenchyma
(19)sclerenchyma.it makes the covering of cells very thick.Because it contains achemica called
(20)chlorenchyma is a part of perenchymatic tissues.it contains chlorophyll.so it gives green colour to plants
(21)simple permanent tissues give a texture to plants but complex tissues are conducting tissues
922) dont know
(23)dont know sorry
I HOPE THOSE ANSWERS THAT I GIVE YOU WILL GIVE YOU A CLUE.IF YOU HAPPY WITH THESE ANSWERS YOU CAN MAKE IT AS BRAINLIEST. SORRY FOR THE MISSING ANSWERS
