A, chloroplast and cell wall.
This is because chloroplasts are what plant cells use to do the process of photosynthesis, which animals do not need. Plant cells also have cell walls.
DNA was discovered during 1953.
Scalar and Vector quantities are Distance and Displacement respectively.
Scalar Quantity is any quantity which has only magnitude but no direction.
It is as follows:
- Distance
- Speed
- Time
- Energy
- Density
- Volume
- Temperature
- Distance
- Work
- Mass
- Frequency
- Direct current
- Entropy
- Refractive index
- Charge
- Electric potential
- Luminous intensity
- Amount of substance
- Pressure
- Power
Vector Quantity is any quantity which has magnitude as well as direction.
It is as follows:
- Displacement
- Force
- Acceleration
- Weight
- Angular Momentum
- Light velocity
- Current
- Gravitational field
- Electric field
- Linear momentum
- Torque
- Polarization
- Centripetal force
- Tension
- Thrust
- Angle
- Drag force
- Impulse
- Alternating current
- Frictional force
