The Edible Onion is naturally a biennial plant, so it takes two years to reach maturity and flower. This means it needs to store food over the winter period, It does this by thickening the bases of its leaves to form a bulb during the first year of growth. The bulb stores sugars and starches for the next growing season and we harvest the onion at this stage to make use of this food store.

Why are onion cells arranged as they are?
Onion cells are arranged in a closely packaged way. This is so
that they layers of the onion can be thick and tough.

Why is the Bulb of the onion plant so big?
It is big because before leaves sprout, the bulb is the source
of food because without leaves, there is no photosynthesis thus no
food unless the bulb feeds the plant (which as I said before, it
does). The bulb of the onion also stores energy. Hope this
satisfies!
Asked in Biology
Why is it that onion leaf epidermal cell do not contain choloroplast?
Because an onion develops in the ground, and chloroplasts
develop in the sunlight. Therefore no chloroplasts form. Think of
it this way: Tree leaves contain chloroplasts because they contain
chlorophyll in order for the leaves to turn colors.
But who has ever heard of an onion changing colors because it's
fall?! Onions dont
needchloroplasts, so they dont have them.
Asked in Chloroplasts
Why do the leaf cells of the onion scale contain no chloroplasts?
Because an onion develops in the ground, and chloroplasts
develop in the sunlight. Therefore no chloroplasts form. Think of
it this way: Tree leaves contain chloroplasts because they contain
chlorophyll in order for the leaves to turn colors. But who
has ever heard of an onion changing colors because it's fall?!
Onions dont need chloroplasts, so they dont have them.
Asked in Chloroplasts
Does onion have chloroplasts in their cells?
The part of the onion you eat is underground. So no, onion has
no chloroplasts in their cells.
Asked in Photosynthesis
Can onions carry out photosynthesis?
Onions themselves are root bulbs, and so cannot
photosynthesize.
Keeping that in mind, onion leaves and the sprouting plant from
the onion bulb CAN photosynthesize like all other leaved
plants.
Hope this helps!

What plants and animals live in thick rain forest?
Different types of monkeys, sloths and plants with big leaves so
they can get sunlight.
Asked in Botany or Plant Biology
Why are the onion cells so close together?
because an onion is a solid.
Asked in Rainforests
What are the layers in the rain forest?
Emergent layer where trees poke higher, canopy layer thick
shelter made by trees overlapping, understory layer where the
trunks and ferns etc are and the floor where more plants, ferns,
baby trees and leaves are, the leaves get so thick that they become
a carpet.
Asked in Geology, Earth Sciences
How are the outer core and the inner core different?
The inner core - the centre of earth - is solid and about 780
miles (1,250 km) thick. The inner core may have a temperature up to
about 13,000°F (7,200°C = 7,500 K), which is hotter than the
surface of the Sun. The inner core (which has a radius of about 750
miles (1,228 km) is solid.
The outer core is so hot that the metal is always molten. The
outer core is about 1370 miles (2,200 km) thick. Because the earth
rotates, the outer core spins around the inner core and that causes
the earth's magnetism. The outer core is in a liquid state and is
about 1,400 miles (2,260 km) thick.

Does onions have photosynthesis?
Onion also a plant. So it is photosynthetic. But onion bulb is
not.

Asked in Biology
Why can't we see chloroplasts in an onion cell?
You can't see chloroplasts in an onion skin cell since the onion
was underground. When the onion is underground, the sun can't reach
the onion so the onion skin cells can't make glucose. The onion
does have chloroplasts in its cells at the top of the onion. That's
where he sunlight can reach the onion.

What are the similarities of the inner and outer core?
the outer core is a molten metal that surrounds the inner core.
In spite of enormous pressure, the outer core behaves like a thick
liquid. The inner core is a dense ball ofsolid metal. In the inner
core,extreme pressire squeezes the atoms of iron and nickel so much
that they cannot spread out and become liquid.

Onion cell function?
the function of the onion cell dictates that they protect the
onion from radiation so if you wear onion skin on your face when
you go in to a radiation chamber you will be safe.
