Plant parts

Acorns are the nut of the oak tree. They start green and gradually go brown as they ripen. Squirrels are very fond of acorns.

A culinary berry is any small, edible fruit, such as strawberries or raspberries. True botanical berries are defined by how the fruit was formed, and neither strawberries or raspberries are true berries.
True berries include blueberries, tomatoes, capsicums, cranberries and grapes. There are many other botanical berries that are not edible. All of these true berries have the fruit made from a single ovary with the seeds inside.

The trunk of a tree is also called a bole. The bole often refers to the lowest, widest part of the tree's trunk.

Branches are parts of a tree that are connected to the main trunk of a tree. Some trees have a very short trunk and lots of thick branches. Most branches are diagonal and point upwards, except in weeping trees where they may droop downwards. A very small branch is called a twig.

A bulb is a part of a plant that is usually below the ground, or partly below the ground. Bulbs are usually quite spherical but pointed at the top like a teardrop. Bulbs grow roots from the bottom and leaves from the top.
Some types of plants that grow from bulbs are onions, lilies and tulips.
Anything that has a similar shape to a bulb may also be called a bulb, such as the bulb at the bottom of an old fashioned thermometer.

A cob is the part of the corn plant that is covered in corn kernels.

Flowers are the part of a plant that is used to make seeds, which grow into baby plants. Flowers are usually very pretty. The reason for this is the plant needs insects to come to the flowers and fertilize them so seeds can develop. Insects are attracted to the flowers by their colour and the sweet nectar that the plant grows inside the flower as a reward for the insects.

Something germinates when it starts to grow. When you are talking about germination you are usually talking about plants. Seeds, bulbs and spores all germinate. The picture is of some coconut seeds germinating.

The kernel is the inner part of a nut or seed. It is also used to mean the small, important part inside a larger thing.

The picture is of popcorn kernels.

Nectar is the sweet, sticky stuff found in the centre of flowers. It is there to attract insects like bees to the flowers so the bees will pollinate the flowers. Bees use the nectar to make honey, most other birds and insects just eat the nectar as they find it.
