The whole apple 4

Stem It held the apple on the tree. Apple growers call the dip it sits in the cavity.
Leaf An apple tree's leaves are oval. They have a narrow point and toothed edges.
Skin A thin layer of natural wax covers it.
Calyx The flower's five sepals, which stay on the apple as it grows. Growers call the dip they sit in the basin.

Cut open 4

Flesh It grows from the base of the flower, around the core. That is why botanists call the apple an accessory fruit.
Core The middle of the apple. Its seed chambers have tough walls, tougher than the flesh around them.
Seeds Each chamber holds one or two seeds. A seed is egg- to pear-shaped, with a blunt or a sharp point.
Carpels An apple usually has five. Botanists call these chambers the true fruit.

How it works

The first drawing is a whole apple. The second shows one apple cut in half from stem to bottom and one cut across the middle, where the seed chambers make a star.

Outside first, then inside

Numbers 1 to 4 are on the whole apple: the stem, a leaf, the skin and the calyx, the dried flower tips at the bottom. Numbers 5 to 7 are inside the apple cut in half: the flesh, the core and the seeds. Number 8 is on the apple cut across: the carpels, the chambers that hold the seeds.

To see the star, cut an apple across its middle, not from top to bottom.
The part you eat is not the true fruit. Botanists give that name to the chambers in the core.

Questions and answers

What are the parts of an apple?

Outside are the stem, the skin and the calyx, the dried flower tips at the bottom. Inside are the flesh, the core and the seed chambers, called carpels. There are usually five, each with one or two seeds.

What is the star inside an apple?

It is the core seen from above. An apple usually has five seed chambers, called carpels, set in a ring. Cut the apple across its middle and they show as a star.

What is the bottom of an apple called?

The dried tips at the bottom are the calyx: the five sepals of the flower, which stay on the fruit. Apple growers call the dip they sit in the basin, and the dip around the stem the cavity.

Is an apple a true fruit?

Botanists call it an accessory fruit, because the flesh grows from the base of the flower and not from the flower's ovary. The true fruits are the chambers in the core.
