Question

I know this is math...but pls some help...
Can we say that one of the differences between animal and plant's cell is vacuole...
They both have vacuole, but in plant cell it is much much bigger than in animal's cell....so?

Answer 1

i think u can say it but u have to tell that in the plant is bigger

Answer 2

k...thnx :)

Answer 3

How abt Photosynthesis...is there any link y can give me so I can learn it better...in my bio. book is pretty messy....:S

Answer 4

haha i dont know links abt bio sorry but i can tell u what is it

Answer 5

Lol...I do know it....but I have to learn it better than wht I already know ...like i said it's pretty messy in my bio. book :(:(

Answer 6

yes you can say that in plant cell, there is one big vacuole, generally occupying 30% of the cell volume.

On the other hand, many animals cells do not vacuole at all. Animal cells which have vacuoles have them in much smaller size but more in numbers.

Answer 7

hmm....thnx :):)

Answer 8

@Harkirat anything abt photosynthesis?

Answer 9

what do u want to know abt photosynthesis???

Answer 10

photosynthesis:the process by which plants use sunlight energy with carbon dioxide and water to produce sugar and oxygen

Answer 11

everything abt it....both reactions(depended from light and not) EVERYTHING!!!

Answer 12

this is the meaning of photosynthesis

Answer 13

I know that Aroub...I've learnt it when i was at 5th grade...

Answer 14

yeah i know me 2 :) haha

Answer 15

lol :P

Answer 16

Well photosynthesis is the process by which green plants and certain algae and bacteria prepare food in the form of starch/sugar by taking in water and carbon-dioxide and combining them with the help of energy taken from sunlight via the green pigment chlorophyll present in the chloroplast.

Answer 17

This reaction can be represented as:

sunlight
6H20 + 6CO2 ---------------> C6H12O6 + 6O2
chlorophyll

so a by-product of photosynthesis is the release of oxygen back into the air

Answer 18

The water is absorbed through the roots by the process of osmosis and the carbon dioxide is directly taken in by the leaves through small openings called stomata. The oxygen is also released into the air through these stomata.

Answer 19

hmmm./...KK..thanks :):):):)

Answer 20

Like we require "heat" for cooking, plants also need energy to prepare their food.

This energy is provided by the green coloured pigment called chlorophyll present in the leaves. It "catches" sunlight and converts it into a form of energy that helps in photosynthesis.

Answer 21

plants make their own food i.e glucose by capturing light energy through a process called photosynthesis photo means light and synthesis means putting together the leaves of the plant contains chloroplast where the glucse is made the cells that contain the chloroplast are found near the upper face of the leaf inside the chloroplas tthere is clorophyl which traps the suns energy and gives the leaves their green colour chlorophyll thus helps the plant in the food making process

Answer 22

thanks for the medal :)

Answer 23

Hence sunlight and chlorophyll are necessary for photosynthesis to occur.

In the light reactions, one molecule of the pigment chlorophyll absorbs one photon and loses one electron. This electron is passed to a modified form of chlorophyll called pheophytin, which passes the electron to a quinone molecule, allowing the start of a flow of electrons down an electron transport chain that leads to the ultimate reduction of NADP to NADPH.


In the light-independent or dark reactions the enzyme RuBisCO captures CO2 from the atmosphere and in a process that requires the newly formed NADPH, called the Calvin-Benson Cycle, releases three-carbon sugars, which are later combined to form sucrose and starch.

Answer 24

Is that sufficient and helpful??????

Answer 25

harkirat do u have any website link anything... abt these things if yes please tell me thank you

Answer 26

Yep!!! :):)
Thnx :):)

Answer 27

well since u asked, i checked n think this a good one
http://www2.estrellamountain.edu/faculty/farabee/biobk/BioBookPS.html

you can always try wikipedia !!!

Answer 28

yes its very good thank you very much :)
