1. Cytoplasm : The fluid present between the cell membrane and the nucleus is called cytoplasm. It is a jelly like substance. Structures like mitochondria,vacuoles, golgi body, endoplasmic reticulum, chloroplast etc. are present in the cytoplasm. These structure present in the cytoplasm are called cell organelles.
2. Nucleus : It is generally spherical. In animal cell, it is located in the centre but in plant cell, it is not located in the centre and shifts towards one side due to large vacuoles. It is enveloped by a double-layered membrane. This membrane is porous and allows the movement of materials. Nucleus contains a small dense structure called the nucleolus. Nucleus contains thread like structures called chromosomes.
