Answer: Option D nutrients
Explanation: at the onset of germination, nutrients is not needed for seed germination. A viable seed has all it it inside of it to grow. For seeds to grow in any environment, they need water, light in some cases, depth of seed planted,temperature in some cases, and oxygen. It is later in it's growth mostly one or 2 weeks that the plant start needing nutrient. Some food crops like vegetables needs nutrients mostly immediately or a day after germination has already occued.
Of course not! There's lots of ways materials can enter. It also depends on the cell; whether it has cell wall and cell membrane or only cell membrane.
Besides diffusion, there's also osmosis and active transport.
If the cell has only cell membrane, it means it's partially permeable, which means osmosis can happen.
