cell membrane and cytoplasm
B
chloroplasts and mitochondria
C
a cell wall and nucleus
D
chloroplasts and cell wall
Explanation: 

Detailed explanation-1: -A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles.

Detailed explanation-2: -Cells are the basic structures of all living organisms. Cells provide structure for the body, take in nutrients from food and carry out important functions. Cells group together to form tissues?, which in turn group together to form organs?, such as the heart and brain.

Detailed explanation-3: -Glycolysis is an ancient, major ATP-producing pathway that occurs in almost all cells, eukaryotes and prokaryotes alike. This process, which is also known as fermentation, takes place in the cytoplasm and does not require oxygen.

Detailed explanation-4: -All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. The plasma membrane, or cell membrane, is the phospholipid layer that surrounds the cell and protects it from the outside environment. Ribosomes are the non-membrane bound organelles where proteins are made, a process called protein synthesis.
