The cell membrane
The outer edge of a cell's cytoplasm is called the cell membrane or plasma membrane. It acts as a boundary that controls the movement of substances in and out of the cell. The cell membrane is composed of a phospholipid bilayer embedded with proteins that help maintain the cell's shape and allow for communication with other cells.
The plant cell has a cell wall outside the cell membrane which gives it a regular shape, unlike animal cells. Inside the plant cell, there is a large fluid filled sac called the vacuole which also helps to maintain the cell's shape and which takes up most of the space that in an animal cell is filled up by cytoplasm. In the little space remaining between the vacuole and the cell membrane, there is the cytoplasm, where the nucleus is found. So the nucleus in a plant cell is found at the edge in the cytoplasm close to the cell membrane!!
on the outer layer of the cell ----------------------------------------- The membrane is found around the edge of a cell - it encases the cell and controls what goes in and out of it. In plants, the membrane is protected by a thick cell wall.
The nucleus is typically located near the edge of the cell to facilitate efficient communication between the nucleus and other cell structures. This positioning allows for quicker transport of genetic information to the cytoplasm for protein synthesis and other cellular processes. Additionally, it may offer protection to the nucleus by keeping it away from potential mechanical stress in the cell's interior.
The edge of a cheek cell is irregular and jagged, while the edge of an onion cell is more uniform and rectangular. Additionally, the cheek cell has a softer and more flexible edge due to the absence of a cell wall, whereas the onion cell has a rigid cell wall that gives it a structured shape.
The outside layer of the animal cell is the cell membrane.

Plant cells have rigid cell walls made of cellulose that provide structural support and prevent drastic changes in shape. Animal cells do not have a cell wall and rely on their cytoskeleton for support, allowing them to change shape more easily.

The outer edge means the furthest most point from the center. The outer edge is usually the end of the object before the dropping off point.

because Onion is a plant. Plant cells have a large vacuole in the centre of the cell which push the surrounding organelles and the nucleus towards the periphery. On the contrary, if you observe an animal cell you will find that the nucleus is situated right at the center because the vacuole is small comparatively and does not occupy a large space at the center.
