How does pollination work?
 The
male part of a plant is the one that produces
the pollen. Some plants rely on the wind to carry
their pollen. Some rely on rain or water to splash the
pollen where it needs to go. The most popular
method is by insects though. Insects, like bees, will
stop by on a flower and when they do this the
pollen sticks to their legs and is transported to the
female part of a flower.

Why do plants need water, sun
and oxygen?

plants use the light energy (with the help of carbon dioxide and
water) to create glucose, a kind of sugar, to keep the plant alive, and
oxygen. Water is needed to make the chemistry behind all life
possible. Plants (and everything else) use water to transport all those
metabolic products to where they are needed and to get nutrients
from the surroundings. Plants also use water to make food for us in
photosynthesis where water molecules and carbon dioxide molecules
combine to form glucose and oxygen. Plants respire exactly the same
way that animals do. If they don't have oxygen plants will suffocate
and die within a few hours.

How will we know a plant is
poisonous?

Take a cutting of that plant, go to your local nursery and get the name of the
plant and either ask them or look it up on the web. If you have children it's
best to get to know what plants are around the play area and if any should be
poisonous it's best to get rid of them.
plant part you choose appears contact-poisonous, you may immediately test
a new plant on your other arm or behind your knee. If the plant causes a
reaction before you swallowed it, wait until the symptoms have disappeared
before testing a new plant.
If you have an adverse reaction after you've swallowed the plant, wait until
symptoms have disappeared and start a new test. Although there may be
edible parts of the plant you initially chose, it is preferable to move on to a
different plant for subsequent tests.

Interesting facts about daffodils


Daffodils are members of the Narcissus family.
All parts of the daffodil are poisonous.
The sap of daffodils can be damaging to other flowers. If you’ve
picked them to display in a vase with other flowers, then it’s best to
leave them in water on their own for at least 12 hours, before mixing
them together.
In New York, nearly 2,500,000 daffodils are grown each year

What’s the difference between a fruit

A fruit is actually the sweet, ripened ovary or ovaries of a seedbearing plant. A vegetable, in contrast, is an herbaceous plant
cultivated for an edible part (seeds, roots, stems, leaves, bulbs,
tubers, or non sweet fruits). So, to be really nit picky, a fruit could be a
vegetable, but a vegetable could not be a fruit. The Nutriquest team
offers a similar answer, adding that most fruits are sweet because
they contain a simple sugar called fructose, while most vegetables
are less sweet because they have much less fructose. The sweetness
of fruit encourages animals to eat it and thereby spread the seeds.
The site also presents an interesting list of fruits that are often thought
to be fruit
tomatoes
cucumbers
squashes and zucchini
avocados
green, red, and yellow peppers
peapods

What do plants need to make food
 There
are a few things that plants need to make
food. Sunlight and water are the most important
resources that are needed in order to for them to
produce food.

Interesting facts about moss/lichen/fern
Moss: They commonly grow close together in clumps
or mats in damp or shady locations. They do not have
flowers or seeds, and their simple leaves cover the thin
wiry stems.

Lichen: A lichen is not a single organism, but the result of
a partnership (mutualistic symbiosis) between a fungus
and an alga or cyanobacteria
Ferns: they thrive in a variety of climates and locations.
These lush, green plants make up a major portion of the
native flora in high mountain forests, as well as tropical
jungles.

 How
dose it work?
 Well, it all begins in the flower. Flowering plants
have several different parts that are important in
pollination. Flowers have male parts called stamens
that produce a sticky powder called pollen. Flowers
also have a female part called the pistil. The top of
the pistil is called the stigma, and is often sticky.
Seeds are made at the base of the pistil, in the
ovule.

In botany a fruit is the developed ovary of a seed-bearing plant. That
would include apples, oranges, peapods, tomatoes, and even nuts.
The term vegetable does not have a particular botanical meaning.
In a culinary definition, a vegetable is a part of a plant (which can
be a stem, a root, a leaf or a fruit) that is generally served as an
accompaniment to meat or fish or as part of the main part of a
meal. Under that definition, some fruits are generally considered
vegetables, like tomatoes or peapods, or green beans. Other fruits,
usually the soft, sweet ones, are generally served as part of dessert or
as an appetizer. There are certainly exceptions, because meats or
fish may sometimes be flavoured with fruits like lemon or orange, but
we still consider those fruits. Nuts are botanically fruits, but we
consider them a separate culinary category. Grains are parts of
plants but not considered vegetables but also a category of their
own. So fruit vs. vegetable vs. something else is not always
completely clear-cut.

They’re one of the easiest flowers to grow and provide a lovely
display of colour in the spring. The emblem of Wales is the daffodil.
People often wear daffodils on St. David’s Day.
In New York, nearly 2,500,000 daffodils are grown each year.
The Victorians thought daffodils acted as a symbol of regard.
Prince Charles, from the British Royal Family, is annually given one
daffodil to act as a form of rent for land on the Isles of Scilly.
Daffodil bulbs contain a substance called galantine, which has
medicinal properties. In fact, it’s sometimes used in treatments for
Alzheimer’s.
In Australia, they have an annual Daffodil Day to help raise
awareness about cancer. The daffodil is also used as a symbol by
Marie Curie Cancer Care in the UK.
