 Recently
room1 and 3 went to the
botanical gardens for a topic trip and we
learnt a lot of new things. We had to ask
questions that we would want to know.
We selected 10 questions and we had to
answer them.
What are the different ways of
dispersal?




Dispersal is when the seeds are spread around and then
the seed grows. Animal Dispersal: the animal dispersal
works by the seed having a prickly outside and when the
animal touches it, the seed sticks to the animal like Velcro
and eventually falls off. Sometimes birds eat the seeds and
then poo them out. And the poo helps them to grow.
Wind Dispersal: Works by the plant seeds being blown
away by the wind.
There are also another way of dispersing the seeds when
the plant explodes and the seeds are fired out and the
seeds can travel at least 1-2 feet away.

What is the difference between a
fruit and vegetable?

The differences between a fruit and vegetables is
that the fruit is actually the ovary of a plant and
mostly have seeds. The vegetables are a plant
part and do not contain seeds although they are
also used in plant reproduction.

of plants, light (either natural sunlight, or from
a light bulb)

collects from the soil through its roots)

What does the word pollination
mean? Explain pollination.


Pollination means that the stigma collects the
pollen of the bees and birds back and that
pollen then feeds the seed in the ovary so
that the seed can last a long time before they
disperse.
Pollination starts what a pollinator (bee or
bird) tries to collect nectar from a flower and
the stamens stick pollen onto them then that
pollinator goes to another flower and the
stigma collects the pollen off the pollinators
back and pollinates the seeds on the ovary.
What is Photosynthesis?
 Photosynthesis
is when plants, some
bacteria, and some protistans use the
energy from sunlight to produce sugar,
which converts into ATP, a "fuel" used by
all living things.

What is the wackiest plant I could
find?
 The
wackiest plant I could find was the
dragon fruit. When you cut it open it looks
like cookies and cream. And the outside
looks like a rose. also known as red
Pitahaya, is a member of the Cactaceae
family and comes from central America.
How do you know how old a tree
is?


To determine how old a tree is you must chop it down
and count how many rings are in the trunk. Or you can
use a coring drill and count the rings then this stops the
tree from dyeing.

Do plants actually breathe?
 Plants
do actually breathe. They breathe
by giving out carbon dioxide and
absorbing oxygen from the surrounding air
through their leaves.

Plant leaves produce 5ml of oxygen per hour. A
car will make around 150ml of co2 per mile (results
may vary).
How does fertilizer work?
 It
supply's the plant with all the nutrients it
needs to grow and it makes it grow faster.
